Rexroth A11VO & A11VLO Series Pump | A11VO145, A11VLO190 | 350-400 Bar High Pressure Pump

Rexroth A11VLO & A11VO Series (Series 11) Heavy-Duty Axial Piston Variable Pump

Product Overview: The Rexroth A11VLO and A11VO series are premium swashplate-designed axial piston variable pumps engineered for high-pressure Open Circuit hydraulic systems. As the flagship of the proven Series 11, these pumps support a continuous rated operating pressure of 350 Bar. The A11VLO version is specifically equipped with an integrated charge pump, granting it superior self-priming capabilities even at high speeds or high-altitude conditions. Whether utilizing LRDS (Power, Pressure, and Load Sensing) control or DRG (Remote Pressure) control, these pumps provide robust and precise power for your heaviest machinery.

Key Technical Advantages:

• Versatile Control Logic (LRDS/DRG):

  • Model A11VO145LRDS: Integrates hyperbolic power control, pressure cut-off, and load sensing, ensuring engine power is optimized across all pressure stages to maximize machine productivity.

  • Model A11VO190DRG: Features remote pressure regulation, allowing operators to modulate system pressure levels seamlessly from a remote station.

• Superior Self-Priming & High-Speed (VLO): The A11VLO series includes an internal charge pump to prevent cavitation issues at high displacements and speeds, significantly expanding the rated speed range and extending service life.

• Heavy-Duty Series 11 Architecture: Built for continuous 24/7 duty cycles. With a rated pressure of 350 Bar (5100 PSI) and peak cycles up to 400 Bar, the reinforced bearing structure handles massive axial and radial loads.

• Robust Thru-Drive Capability (NZD/NTD): Advanced thru-drive performance indicated by codes such as NZD12 or NTD12 allows for tandem mounting of secondary pumps, facilitating compact multi-circuit power distribution.
